ImportantSafetyInstructions,CareandHandling
Before starting, take a few minutes to read this manual.
Read all of these instructions and save this manual for
later reference.
Protect the disk array system from extremely high or low
temperatures. Let the disk array system warm (or cool)
to room temperature before using it.
Protect the disk array system from being bumped or
dropped. Do not place the disk array system on an
unstable cart, stand, or table. It may fall, causing serious
damage to the product.
Keep the disk array system away from magnetic forces.
Do not use the disk array system near water.
Keep the disk array system away from dust, sand, or dirt.
Gaps and openings in the cabinet are provided for venti-
lation. Never block or cover these openings, because
the disk array system may overheat and become unreli-
able. Don’t place the disk array system on a bed, sofa,
rug, or other similar surface.
Do not place the disk array system near or over a radia-
tor or heat register.
Refer to the rating plate for the correct voltage and
ensure that the appliance voltage corresponds to the
supply voltage.
V

The appliance must be grounded. The disk array system
is equipped with a 3-wire grounded type of power cord.
This power cord will only fit into a grounded type of
power outlet.
If an extension cord or a power center is used with the
disk array system, make sure that the total current con-
sumption of all products plugged into the wall outlet
does not exceed the ampere rating.
Do not place the disk array system where the cord will
be walked on.
Never push any kind of object into the disk array system
through cabinet gaps and openings, since they may
touch dangerous voltage points and cause a risk of fire
or electric shock.
Unplug the power cord from the wall outlet before clean-
ing. Keep the disk array system dry. Do not use liquid
cleaners, aerosol cleaners, or a wet cloth. Use a damp
cloth for cleaning.
Except as specifically explained in this User Manual, do
not attempt to service the disk array system by yourself.
Opening or removing the covers may expose you to
dangerous voltages.
Unplug this product from the wall outlet and refer servic-
ing to qualified service personnel under the following
conditions.
• If the disk array system has been exposed to
water or any liquid.
• If the disk array system has been dropped or the
cabinet damaged.
User should not remove the cover.
Disconnect all power supply cords before servicing.

This chapter introduces the features and capabilities of
subsystem.
You will find:
ÖA full introduction to your subsystem
ÖDetails of key features
ÖA list of the product specifications
Overview
Congratulations on your selection of the subsystem. The subsystem is a
high-performance and extremely flexible RAID subsystem. RAID (Redundant Array of
Independent/Inexpensive Disks) is a storage technology used to improve the processing
capabilities of a storage system, providing a combination of reliability and performance.
This is ideally suited for integration with databases, e-mail, web servers and imaging
systems.
This is the ultimate approach to a flexible RAID solution. It can manage three different
RAID levels (0, 0+1 and 5) and also offers the option of RAID 5+hot spare. You will find
detailed explanation on the features and suggested uses of these RAID levels later in this
chapter.
The subsystem features a user-friendly drive carrier design that lets you easily install
four drives. Each drive carrier supports a one-inch high 3.5-inch form factor drive.
Featuring intelligent online recovery, the lets you hot swap a failed drive: data will
automatically be rebuilt to the new drive without any system down time. The four drive
design allows also one drive to be designated a hot spare: if one of other drives fails, the
will seamlessly rebuild the failed drive’s data on the hot spare.

Key features
The subsystem supports the following features
zAutomatic on-line rebuilding
zDrives are hot swappable
zSupports RAID levels 0, 0+1 and 5
zOptional hot spare setup for RAID 5 (5+spare)
zHot swappable fan
zSupports four Serial ATA hard drives
zRequires no driver
zAudible alarm on drive failure & alarm mute function
zSupports multiple host interfaces
zDisk auto shutdown when system over heat for protecting.
zPlug and play
Hot Spare
Hot Spare allows for the automatic replacement of a failed drive without requiring
intervention from the administrator. If this option is selected and a drive fails, the will
automatically replace the faulty drive with the hot spare drive.
Automatic drive rebuilding
If a member drive in a RAID 5 array is replaced on-line, the controller will automatically
start to rebuild data to the new drive.
Hard drive hot swapping
Hot swapping allows for the removal and installation of disk drives without the need to
power down the system while the system is in use.
Multiple host interface support
The subsystem is available in two hardware configurations so that users may select the
host interface most appropriate for their system. The two configurations offer the
following host interfaces:

Chapter 1 – Introduction
-1-3-
zIEEE 1394A/B (also known as I. Link and FireWire)
zUSB 2.0
Auto disk shut down when over heat
The will shut down disks automatically when temperature is over 55 oCto prevent the
damage of DISK and DATA loss.
This manual contains the information necessary to set up each of the two
available hardware configurations of the subsystem . Where procedures for
the configurations differ, they are described separately and clearly marked.
